Where do these Cookies come from?

PHP

I’m using PHP to set certain cookies (PHPSESSID among them), but several other cookies appear for the same site, called ‘_utma’, ‘_utmb’, ‘_utmc’ and ‘_utmz’. They have expiry dates ranging from ‘end of session’ to two years hence. They don’t seem to contribute anything to the running of my code.

Cookies with similar names appear for other sites (where I’m only a visitor).
I’m just curious to know how they appear, and for what purpose. Are they to do with MySQL, perhaps ?

Ah, Yes, thank you, that would seem to be the case.

I’m guessing you’ve got google analytics attached to your page.

Guess where they come from…

Looks like those are Google Analytics cookies.
